What does mailing list processing, or CASS Certification, include?
When you purchase mailing services, we will review your mailing lists in order to remove duplicate contacts (if requested) and remove any undeliverable addresses through the CASS certification process. There is no additional charge for reviewing your mailing list to remove these items, but it is an optional service that must be specified within the Upload List process. If you request removal of duplicates, keep in mind that the software only looks for EXACT matches, so “John Smith” versus “Jonathon Smith” will not be recognized as a duplicate record.
